[Blindmath] great question...Re: Economical tactile graphics - Microcapsule or Swell Paper in a microwave oven?

[Pranav Lal]

Hi all,

I have used German film on one of those rubber mats with a stylus for
inexpensive tactile graphics. My problem was that labels were hard to
produce and I had to do freehand drawing. Yes, I had standard geometry
implements which I used for math class.

For uniform heating, how about using a solar cooker?
